I Rhodium plate some 20 to 40 rings per day and I would like toknown how to keep the solution working consistently.

I have used a coffee filter to clean the solution and added theDistlled Water along with the Rhodium replenisher. This works for awhile. Is there a solution that stays consistent? Is there someother Rodinum that works better?

Johneric - thats alot of plating i do only one to five rings a dayaverage but its been suggested to me and i am using pen platingsoloution to replenish it sounds to me though that you use enough ofthis stuff that it may be in your best intrest to mix your ownplating soloution. i know people who have a diamond tool bit companyand they make thier own plating soloutions. i am sure the info is outthere somewhere to make rhodium into a salt for plating.

This works for a while. Is there a solution that stays consistent?

Maybe someone will post some great solution In general, though,when you rhodium plate (or any plate), you are actually taking metalout of solution and putting it on your work. We all wish that themetal in solution was eternal, but it's not. There's no free ride,especially with rhodium. Now a friend who plates a lot keeps his oldsolutions that are clean and lets them evaporate till they turnorangey-brown, and uses them for replenisher. Just one way...

As John wrote, his friend lets his used solutions evaporate untilthey turn orangey-brown. As a chemist, that's really the only way Ican think of (without huge pieces of extortionately expensiveanalytical chemistry type equipment to measure things accurately) tomake use of previously used plating solutions. As he says, you aretaking metal atoms out of solution and putting it one your work andso there is less metal in the solution once it has been used and sothe solution is a much less concentrated metal solution. But, as hisfriend does, if you let some of the solvent (the liquid the metal isdissolved in) evaporate, until it is roughly the same colour as itis intended, then you will achieve a roughly correct concentration ofmetal solution that you can use to add to the plating bath. You justhave less volume, but it'll make your plating solution go furtherthan it would otherwise.
